Changing Depreciation rates in Ax 4.0

I need to change the depreciation rate - the value model - for several assets in AX 4.0.

(eg from 10% to 20% straight line)

The relevant value models are set up - sl10 & sl20 .

What is the general procedure for this -

I tried splitting the asset 100% from one value model to another value model - but this doesn’t seem to work.

Splitting FA is generally accepted approach in this case. I guess following link will help you:!/2012/05/how-to-transfer-fixed-asset-and-its.html
